Very nice! Love the colors. Very dainty. I think if you just add (the equivalent of the) blocks to the top and bottom a row at a time you could see what it would take to keep the "L" in the middle.
It looks very nice so far, I think continue on with some of the same blocks would make it as you wish it to be. A few more rows of patches around what you already have done :).. very nice :)
